C++ . Accessing Objects and Setting Values - c++

Question

Hello StackOverflow community.
I cant seem to change a value on a class.
I am new to C++, and I have been looking for a solution but I cant seem to figure it out.
This is my Account.cpp
#include "Account.h"
#include <iostream>
using namespace std;
Account::Account(string accName, int accBalance)
{
name = accName;
balance = accBalance;
std::vector<std::string> Report();
}
bool Account::Deposit(Account a,int amt) {
if (amt >= 0) {
a.balance += amt;
return 1;
}
else
return 0;
}
bool Account::Withdraw(Account a, int amt) {
if (amt >= 0 && (a.balance - amt > 0)) {
a.balance -= amt;
return 1;
}
else
return 0;
}
int equal(string a, string b) {
if (a == b) return 1;
else return 0;
}
Account::~Account()
{
}
This is my main.cpp
int main() {
int aux_bal;
string aux_name;
int choice;
std::string InputName;
std::list< Account > arr;
std::list<Account>::iterator result;
do
{
cout << endl
<< " 1 - Create New Account.\n"
<< " 2 - View Balance.\n"
<< " 3 - Make a Deposit\n"
<< " 4 - Make a Withdraw\n"
<< " 5 - Check log\n"
<< " 6 - Exit.\n"
<< " Enter your choice and press return: ";
cin >> choice;
switch (choice)
{
case 1:
cout << "Input holder's account name: \n";
cin >> InputName;
arr.push_back(Account(InputName, 0));
break;
case 2:
cout << "Enter Account Name:\n";
cin >> InputName;
for (result = arr.begin(); result != arr.end(); result++) {
int aux_bal = result->balance;
std::string aux_name = result->name;
if (aux_name == InputName) {
cout <<"Account Balance:"<< aux_bal << endl;
cout << "Account Holder:" << aux_name << endl;
}
}
break;
case 3:
cout << "Enter Account Name:\n";
cin >> InputName;
for (result = arr.begin(); result != arr.end(); result++) {
int aux_bal = result->balance;
std::string aux_name = result->name;
if (aux_name == InputName) {
cout << "Enter ammount to Deposit:\n";
cin >> aux_bal;
(*result).Deposit(*result,aux_bal);
}
}
break;
case 4:
//code to help the user like give him
//extra information about the mode and the controller
break;
case 5:
break;
case 6:cout << "End of Program.\n";
break;
default:
cout << "Not a Valid Choice. \n"
<< "Choose again.\n";
break;
}
} while (choice != 6);
return 0;
}
For some reason when I output the account info after making a Deposit, the Balance value remains unaltered at 0.
Any help please?

Answer 1

The deposit function should act on the account object that it belongs to, you don't need to pass it as an argument. Also, integers are not booleans. Lastly, why is the deposit amount an int? What if I want to deposit $20.25 ?
bool Account::Deposit(int depositAmt)
{
if (depositAmt >= 0) {
this->balance += depositAmt; // "this->" is optional
return true;
}
else
return false;
}
